ON THE POST-EMBRYONIC DEVELOPMENT OF FUNGIA.

College, Oxford. 
[Abstract of a Paper read June 21, 1893; published im extenso in the SCIENTIFIC 
TRANSACTIONS OF THE Roya Dusuin Society, Vol. V.] 
I am indebted to Professor A. C. Haddon for a fine collection of 
Fungie in all stages, brought back by him from the Torres Straits, 
an examination of which has enabled me to give a detailed descrip- 
tion of the various phases in the life-history of this coral. For 
convenience sake I have adopted the following terms, descriptive 
of the various structures in the young and adult Fungiz :— 
Trophozooid.—The individual Caryophyllia-like form developed 
directly from the ovum. This may give rise by budding to one or 
more— 
Anthoblasts, by which name the buds are conveniently distin- 
guished from the individual which gave rise to them. 
Anthocormus.—Two or more Anthoblasts united to form a 
stock or colony. 
Anthocyathus.—The discoid Fungia form, whether free or 
attached, developed from a Trophozooid or an Anthoblast. 
Anthocaulus:—The pedicle which carries the Anthocyathus, 
and, after the detachment of the latter, remains in connexion 
with the Cormus, or is attached to a foreign body, and usually 
gives rise, by re-growth, to a new Anthocyathus. 
The Trophozooid may remain solitary, and give rise to a 
succession of Anthocyathi; more usually it gives rise by budding 
from the extrathecal soft tissues to a number of Anthoblasts, 
which form a stock or colony. Under exceptional circumstances 
buds may also be formed—(1) from the truncated distal end of 
an Anthocaulus, (2) from the scar on the aboral surface of a 
recently detached Anthocyathus. Longitudinal division of the 
calyx ofan Anthoblast has also been observed.
